I have a simple script in Python which I run in Rhino3D. It shows a message box as following :
import ctypes # An included library with Python install.
ctypes.windll.user32.MessageBoxA(0, "Your text", "Test", 1)
Moreover, it shows only the first letter of each of my text (title and content). How can I solve it ? What is the reason ? Is the problem coming from Rhino3D ?
